Notes:
3. tPSK is equal to the magnitude of the worst case difference in tPHL and/or tPLH that will be seen between units at any given
temperature within the recommended operating conditions.
4. Common mode transient immunity at output high is the maximum tolerable (positive) dVcm/dt on the leading edge
of the common mode impulse signal. Vcm, to assure that the output will remain high. Common mode transient
immunity at output low is the maximum tolerable (negative dVcm/dt on the trailing edge of the common pulse
signal, Vcm, to assure that the output will remain low.
